I have just purchased a late 1960 heathkit amp it seems that it was modified by J Reevs who seem to have made the enclosures , The problem I have is finding a circuit diagram for it. The front panel states heathkit transistor TS-23. But a web search finds a heathkit power supply ?
can anyone help

No schematic but this advert from 1968 seems to prove that the Heathkit TS-23 amplifier does exist. It could be bought (as a kit) without a cabinet.

The advertisement shows a low cost 3 watts per channel amp. I suspect that they didn’t sell many. There was a mention a few years ago of a website that had many manuals but I can’t remember what it was.
If your amplifier has been modified then I doubt you will find a correct diagram.

This may be the website you're referring to, but TS-23 is not listed:-
